Triopha catalinaeSea-clown triopha
Eastern Pacific species ranging from southeast Alaska to norther Gulf of California. Very similar to T. modesta, but can be diferentiated by unbranched dorso-lateral appendages and tubercles. T. modesta exhibits branching on both and has a trans-Pacific distribution from the Sea of Japan to Southern California. Both species have white-translucent bodies with orange appendages, rhinophores, and tubercles. Orange or grey-bodied colour morphs can occur.
Max Size: 12 cm
Sea Temperature Range: 13.1-19.6°C
Habitat Generalization Index: N/A
Also referred to as the SGI (Species Generalisation Index), this describes the habitat niche breadth of the species. Species with values less than 15 are found in a relatively narrow range of reef habitat types (specialists), while those over 25 may be found on most hard substrates within their range (generalists).

Conservation and Rarity
IUCN Status: Not Evaluated
Occurrence: Common (22.2% of sites)
Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed
Abundance: Few (3 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
